DESIGN OF CHENAB BRIDGE IN INDIA

Abstract

The Chenab Bridge's conceptual design and structural design principles are described in this study. The major goal is to describe the unique bridge concept in difficult terrain and to provide an overview of the design solutions employed in one of the world's tallest steel arch railway bridges. The construction of a new railway line in India has been taken on by Indian Railways as a mega-project in the state of Jammu and Kashmir. The project includes a large number of tunnels and bridges which are to be implemented in highly rugged and mountainous terrain. The alignment crosses a deep gorge of the Chenab River which necessitates construction of a long span railway bridge. The deck height is 359m and bridge length is 1315m. Indian railways constructing the iconic arch bridge on river Chenab as a part of the USBRL project to connect Kashmir valley to the rest of nation. Arch bridge completely made of steel. Foundations and the approach viaduct piers are made of concrete. This paper describes the design and engineering of the bridge. The bridge has numerous design challenges such as erection of the steel arch by cable crane, the bridge’s huge dimensions, and the special design requirements- redundancy of the arch, the earthquake load and blast load effect. The challenges in the design and erection of the bridge is described in this paper.bridge, long-span, railway, arch
